David Meier, an attorney appointed to lead a review of drug cases in the wake of a scandal at a Massachusetts State Police drug-testing lab, speaks to reporters in Boston, Friday Oct. 12, 2012, where he said many of the 34,000 defendants who could be affected have already served their time or otherwise had their cases resolved. Former state chemist Annie Dookhan is charged with obstruction of justice for allegedly failing to follow testing protocols and altering results at the now-closed lab. (AP Photo/Elise Amendola)
